What a Double Deck Booth Is
A double deck booth adds a second level above part or all of the exhibitor's floor space. The upper deck is reached by stairs inside the booth and is usually used for meeting rooms, hospitality or a lounge, while the ground floor carries demos and walk-in traffic. Because it is a built structure people stand on, it is treated differently from any other exhibit: venues, fire authorities and organizers all review it before it goes up. The trade show booth types guide shows where it sits among inline, peninsula and island space.
| Item | Single-level island | Double deck island |
|---|---|---|
| Usable space | Floor area only | Floor area plus the upper deck |
| Typical use | Demos, meetings, hanging sign above | Ground-floor demos, upper-level meetings or hospitality |
| Drawings | Often required for large custom builds | Stamped structural drawings, almost always required |
| Fire review | Covered areas and materials | Covered areas, both levels, exits and occupancy |
| Move-in time | Standard island window | Often longer, with lifts or forklifts |
Which Booth Spaces Allow a Double Deck
A second level blocks sightlines on every side and needs room for stairs, so almost every show limits double decks to island booths. Many also set a minimum island size and restrict double decks to halls where the ceiling height, sprinklers and rigging allow them. Check the venue's own rules before you promise anything in the prospectus: some halls cap structure height or forbid multi-story exhibits under certain ceilings.
- Island booths only, with a minimum size you set (for example 20x30 or larger)
- Only in halls or zones the venue approves for multi-story structures
- Not directly under low ceilings, chandeliers, rigging points or sprinkler obstructions
- Not beside an entrance or fire exit where the structure would block sightlines to exit signs
- A setback from neighboring booths so the upper deck does not overhang their space
Rules Organizers Set for Multi-Level Booths
- 1
Structural Drawings and an Engineer's Stamp
Require drawings stamped by a licensed structural engineer or architect, showing load ratings, stairs, handrails and the deck's footprint. Ask for them by a firm deadline, as a rule of thumb 60 to 90 days before move-in, so changes can be made before the build.
- 2
Upper Deck Capacity
The upper deck needs a posted maximum number of people, based on the engineer's load rating and local code. Ask exhibitors to state it on the drawings and post it at the stairs.
- 3
Fire Marshal Requirements
Covered areas, both levels and the stairs are subject to fire marshal review. Expect requirements such as fire extinguishers on each level, smoke detection under large covered areas, flame-retardant materials and, above a certain upper deck size, a second stairway. Local code sets the thresholds; see fire marshal floor plan requirements.
- 4
Height Limit
Set a maximum overall height that fits the hall and your island rules, and say whether hanging signs are allowed above a double deck. See booth height restrictions for choosing the numbers.
- 5
Build, Inspection and Insurance
Require the exhibit builder to be on site for the build, an inspection before the upper deck is used, and proof of insurance that covers the structure.
- 6
Second-Level Fee
Decide whether the upper deck is included in the island price or charged per square foot. Many organizers charge for it, because it adds sellable meeting space for the exhibitor.
How to Price the Second Level
Charging for the upper deck is an organizer pricing option, not a requirement. If you do charge, tie it to the deck's square footage and publish it next to your island rates. The figures below are planning assumptions only, built on an example $35 per sq ft island rate; use your own rate card.
| Option | How it is priced | Example: 30x30 island with a 400 sq ft upper deck |
|---|---|---|
| Included | Upper deck included in the island price | $31,500 (900 sq ft x $35) |
| Half the floor rate | Upper deck at 50% of the island rate | $31,500 + $7,000 = $38,500 |
| Full floor rate | Upper deck priced like floor space | $31,500 + $14,000 = $45,500 |
| Flat fee | One fee per double deck, whatever its size | $31,500 + $5,000 = $36,500 |

Showing and Selling Double Deck Space on the Floor Plan
- 1
Map the Ceiling First
Draw the hall to scale with ceiling heights, low points, chandeliers and rigging points marked, so you only offer double decks where they can be built.
- 2
Label Eligible Islands
Mark islands that allow a second level with their own booth type or color, and say so in the booth description exhibitors read before they buy.
- 3
Place Them Where Height Helps
Place double deck islands where their height helps the hall, such as the center or the back, rather than right inside the main entrance where they block the view of the floor.
- 4
Plan Move-In Around Them
Leave wide aisles around double deck islands for lifts and forklifts during move-in, and give them an earlier move-in window in the schedule.
If you sell island space online, show the double deck allowance and the second-level fee in the booth details so exhibitors don't discover the rule after they pay. Trade show management software covers the rest of the show, from the floor plan to exhibitor communication.
